RIM-JOINT FOR VEHICLE-WHEELS.

atent No. 579,673, dated March 30, 1897.

Serial No. 558,104. (No model.)

To ctZZwhom it may concern.-

Beit known that I, EDWARD B. DAKE, a citizen of the United States, and aresident of Muskegon, in the county of Muskegon and State of Michigan,have invented certain new and useful Improvements in Rim-Joints forVehicle-Vheels; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters of referencemarked thereon, which form a part of this specification.

Figure 1 of the drawings is a perspective view of wheel-felly with theinvention applied thereto. Fig. 2 is an enlarged perspective of the twosections of the felly to be joined. Fig. 3 is a plan view of one of thesections.

This invention has relation to a joint for the wood rims or fellies ofvehicle-wheels, and has for its object the provision of a joint whichcannot be pulled apart in a sidewise direction, and which is strong andrigid.

WVith this object in view the invention consists in the novelconstruction and combinapointed out in the appended claim.

Referring to the accompanying drawings, the letters A and B designatetwo sections of a wheel-rim or felly which are united in accordance withthis invention. Each of said sections is provided at its end with aseries of parallel interlocking tenons, as a, which conform to thegeneral contour or curvature of the rim and which fit between acorresponding series of tenons on the opposing section'which, fordistinction, are marked b. In the present instance I have shown eachsection as having three of these tenons, but I do not wish to be limitedto any particular number.

The tenonsare of equal thickness throughout their length, and theirlateral faces are parallel and vertical, and the end of each iscontinuously beveled from its upper to its lower surface, as at 0,adjacent tenons having directly opposite bevels. The abutments for saidtenons are also alternately beveled, as at d.

This feature of beveling the ends of the tenons enables the joint tohold glue much better than would be the case were they formed withsquare abutting ends. It also greatly strengthens the joint. Theopposite bevels hold the sections from all tendency to buckle eitheroutward or inward and renders it impossible for the sections to separateexcept by a direct longitudinal movement away from each other. It willalso appear that this feature greatly strengthens the joint owing to thefact that the wood between the tenons is not entirely cut away, but isleft to increase the strength of the abutments, and that this increaseof strength is distributed equally upon both the upper and lowerportions of the joint and upon opposite sides of the transverse centerof the joint, adjacent tenons being of different lengths upon the sameside of the joint and their end bearings upon the beveled walls of theinterspaces of the opposing section being at different points withrelation to such transverse center.

I am aware that it is not broadly new to form a rim-joint having aseries of interfitting tenons, as instances of such joints are shown inthe English Patents No. 503 of 1895 to Cooley and No. 7,062 of 1894 toMarble; also in the United States patent to Rastetter, No. 528,741, ofNovember 6, 1894:, and I hereby disclaim the constructions shown inthose patents. The present invention is clearly distinguished from thejoint shown in the said English patent to Oooley in that the beveledabutments between the tongues or tenons are not extended to form asecond lower set of tongues or tenons which are opposed to the first orupper set, the tongues or tenons of both sets being ofgradually-decreasing vertical thickness which renders them less strong.I11 the present construction each tongue or tenon maintains its fullvertical thickness to a point near its end where the bevel commences.The invention is distinguished from the joints shown in the said patentsto Rastetter and Marble in the features of its beveled ends, which, asabove pointed out, greatly increases the strength of the joint anddecreases its tendency to buckle in either direction. The invention isalso distinguished from the said patents in the feature whereby adjacenttenons are oppositely beveled, which also greatly adds to the the rearWallsof the interspaces of each end strength of the joint. being beveledalternately in opposite direc- Having thus described my invention, whattions to correspond with these engaging pro- I claim as new, and desireto secure by Letters jeetions.
